Abstract

A windshield cleaning system with a washing system includes a washing liquid pipe non-rotatably fixed in a bore of a wiper shaft, the end of which washing liquid pipe is inserted into a pot-like connecting piece protected against twisting. Thereby the connecting piece is bracelessly centered with respect to the end of the washing liquid pipe so that it can also make a possible wobbling movement of the end in radial direction. Thus a long lifetime of the connecting point between the rotating end of the washing liquid pipe and the non-rotatable connecting piece is achieved.
